Car rental transaction days measure the number of days, or portions of days under the issuer's definition, that rental vehicles are generating revenue.
Avis Budget calls the metric rental days. Hertz calls it transaction days.
Transaction days are the volume leg of rental revenue
A simplified rental-revenue bridge is:
rental revenue ≈ transaction days × revenue per day
Hertz reported 38.6 million transaction days across its Americas and International rental businesses in the second quarter of 2026.
Avis Budget reported 43.9 million rental days for the same quarter.
The absolute figures should not be compared without considering fleet size, geography, brand mix, and issuer definitions.
Partial days can matter
Hertz defines a transaction day as a 24-hour rental period, with any partial period counted as one transaction day.
That means one vehicle can generate more than one transaction day within a calendar day if one rental closes and another begins.
This is one reason the metric should be interpreted using the company's own methodology rather than as a simple physical-day count.
Volume and fleet size are separate variables
A company can grow transaction days by expanding its fleet, by improving utilization of an existing fleet, or both.
That distinction matters because fleet growth requires capital and financing while utilization gains increase productivity from vehicles already available.
Car Rental Vehicle Utilization connects transaction days to rentable fleet capacity.
Higher transaction days are not automatically better
Volume growth can be unprofitable if it requires weak pricing, excessive fleet growth, or costly incentives.
Investors should compare transaction days with Car Rental Revenue per Day, fleet cost, utilization, and revenue per unit.

Car rental transaction days are most useful as the physical-volume leg of rental demand, not as a stand-alone measure of pricing or profitability.
